If they're the kind of customer that sees the USB port as a plus they are going to be mighty unhappy right quick when they start running out of 120 vAC outlets, probably within the first day or two of occupancy. Heck, there are plenty of places in my house I wish I had a 4-gang box.
So true, when I wire my son's remodel I used plenty of quads where he intended to group his sound and video stuff to reduce the need for power strips. An still he needed to use a few power strips. Also, because of the electronics the power to those outlets were feed from the same lineside of the panel such that no outlet in that area were not 240v appart.
In a bedroom, the nightstand dresser next to the bed may include more than the basic clock radio and lamp which is another place a power strip is used. I also anticipate that the kitchen may need extra outlets because of the number of appliances as well as the outlets being closer together because of those pesky short power cords.
But, this certainly wasn't a bit job where being competitive and profit are an issue.
